 ### Extract from MODS using XPath
 
 Site admins can configure multiple MODS elements in a preferred order by entering XPath expressions in the admin setting's "XPath expressions to MODS elements containing map data" field. Data from the first element to match one of the configured XPath expressions is used to render the map. The module provide sensible default values that prefer `<subject><cartographics><coordinates>` over `<subject><geographic>`.
